Specification of Letters Patent.

Patented July 23, 1918.

Application filed June 25, 1914. Serial No. 847,302.

To all whom it may concern:

Be it knownthat I, OBERLIN SMITH, of Bridgeton, in the county ofCumberland, and in the State of New Jersey, have invented a certain newand useful Improvement in Presses, and do hereby declare that thefollowing is a full, clear, and exact descri tion thereof.

y invention relates to presses employing a reciprocating tool-carryingram and in particular to presses in which a plurality of operations maybe simultaneously performed, and the object of my invention is generallyto improve the construction of presses of this class in. such matters asease and convenience of access to the tools, multiplication of thenumber of operations that may simultaneously be performed, increasingthe strength or stiffness of the structure, while at the same timerendering it compact, and simplifying and lessening the cost ofconstruction, and to attain this object and provide a press having otheradvantages which those skilled in the art will readily appreciate, myinvention consists in the press having the construction substantiallyashereinafter specified and claimed.

As it will be recognized my invention may be embodied in structures ofvarious forms, but it will sufficiently illustrate my invention to showone embodiment thereof, and in the accompanying drawings- Figure 1 is afront elevation of a press embodying my invention;

Fig. 2is a side elevation thereof;

Fig. .3 is a vertical section from front to rear;

Fig. 4 is a top plan view;

Fig. 5 is a horizontal section on the line 5-5 of Fig. 3, in a planejust above the diecarrying dial, a portion of the latter being brokenaway to reveal the structure below;

Fig. 6 is a detail view in vertical section of the cork feeding device,the press shown to illustrate my invention being one for the manufactureof the familiar bottle closure composed of united disks of sheet metaland cork.

Referring to' the drawings in connection with a detailed description ofthe press shown, it will be found that the bed or frame 10 is in theform of a vertical standard to the top of which is secured a table 11.Upon the top of the table is journaled a horizontally rotatable dial 12having a circular series of holes 120 each for the reception of theblank or work, beneath which the bed is provided with a circular seriesof dies 13, the press shown being one in which the tools consist ofcooperating punches and dies and the punches being carried by a ram 14.The ram 14 passes centrally through the dial and table having above thedial a head 15 in the form, as shown, of a disk with a series .of radialnotches, or slots in its periphery,

or circumference, each of which is adapted to detachably hold a suitablepunch,,or tool to cooperate with an alining die below. The ram has abody, which for convenience of construction is preferably cylindrical,which has a sliding lit in a bearing in the upper part of the standard,said bearing being in the form of a sleeve 16 which is mounted in theupper part of the standard and externally has a tapering, or conicalform so that When a nut thereon is moved longitudinally (it being asplit sleeve) it may be adjusted to secure the desired bearing fit andto compensate for wear. As the ram-reciprocating means is below the dialsupporting table it will be seen that there is no frame structurerequired that conceals, or obstructs access to the tools, but the latterabove the dies and punches areso completely exposed that the fullestpossible access thereto is possible and the number of tools that may beprovided is not diminished, or reduced, as would be the case with suchan arrangement of the frame structure, as would house, or cover portionsof the toolcarrying head and dial.

Since the bearing body of the ram is cylindrical in the case of thepress shown, I provide a stud or post 17 which is attached to the ramhead and passes through a hole 18 in the table which it slidably fitsand thereby the punch-carrying head is prevented from rotating.Obviously, if the ram body were given a rectangular, or other flat sidedform no device, such as the stop or post would be necessary to preventit from rotating.

A very important advantage from my construction is the possibility ofmaking the ram of great length compared with the height of the press,that is to say, without enlarging the size of the press, but on thecontrary providing a very compact structure,

the ram can be of such great length as greatly to add to the stifinessof the structure and preclude laterial lost motions of the ram.

i'The ram-reciprocating crank shaft Q'Ois 10urnaled 1n horizontalbearings an the press frame, being provided at oneend with a pui l eyandfly wheel 1'9. 'Moun'ted on the erank portion of the shaft is apitin'an .bloek 21 ito which :i'ssecured arod that projects on oppositesides t hereof right angles to the crank shaft, and slidably engagesopenings in the shank, -'or stem of the pensatefor defectsofconstructionsothat nc greatpains need be taken *by the work man-- for'accurate constructionby machining parts, for other olose work so that;nothing beyondgordinary workmanship is required. The dial is rotatedstep my step to carry -the =workfroni die to die, and for this purposeits periphery is provided with ratchet teed-i 23 -agd'a pted' to beengaged by a feed pawl-124 carried by" {a "rocking 'lever 25 mounted torock on a horizontal pivot-26 projedting from the side oilf thestandard. llhe'lo'wer end 27.01? the lever is slotted and theslot is acrank pin 28 upon the crank 'sh'a ft 2t). i 'As' hasbefore'beenstated,the-;press illustrating one einbodiment of my invention is used in theina r'iufacture of bottle closures. These are ina'de of -disks-of metal,ai aX p aper and/"cork; f l lre ;paper -i%n strip form Wound into a rolliis fsu ppor'ted by a reel, the strip being carried from the latter andpassed between a "pair of feed rollers, 29 journaled horizontallyinbearings on'the top of the table, and for operating the feed rollers{one ofthem hasupononetend a rat'chetwh'eel -30 adapted to be actuatedby a suitable pawl 13d. :Said-pa-Wliscarriediby a rocking arm '32 whichby arod or ;pit1nan 83 is connected ivi tlrthe"dial'f-dndeXing-ilever25.

Mea'nsmreprovidedfor ing devices which may have the form and -=arrangement bestshown in -Fig. 5. The

table 11 of the press immediately below the dial has two segmentalrecesses in which, respectively are placed -a' curvi l i=near heatingpipe 34' that is-suppliedwith steam'and a curvilinear coolingpipej'345'0 which is supplied :with cold water. The disks by the rotation oftihe dial are earried above the heating and/cooling pipes, -andare thereby subjected to their influences so that, first, they areheated, and thereafter are cooled.

The eork .disks eareplaced. in a stack, or pile in a vertical tubularreservoir 35, "which is supported on the top of the press table with its'l-owerend {in position to diseharge a. i cork disk at a time to thestop of the dial in position'to be engaged by a reciprocating feed bar,or slide 36, which engages the lowerinost cor-k and slides" it into"position b'e'-,
